Gaga, Cyndi Lauper, Nicki Minaj and the original MAC Girl RuPaul have all done it, but now it’s RiRi’s turn. Rihanna has a limited edition collabo with the cosmetics juggernaut that comes out at later in the year. She’ll start with a lipstick called RiRi Woo which is inspired by MAC’s Ruby Woo, Rihanna’s fave color. The lipstick will be released May 4th and they will sell it at her concerts and online and let me tell you, these collabos always sell out fast. Nicki’s Pink Friday sold out almost immediately after it went up so be ready y’all. Personally? I’m eyeing that brush.
